Personalized Image Capture Technology (.pct)

The PCT (Personalized Image Capture Technology) file extension, developed by Apple in 1984, is a graphics file format used primarily for exchanging images between Macintosh applications. It supports both vector and bitmap graphics and was the native format for the QuickDraw graphics library. Over time, PCT has been largely replaced by PDF, but it remains supported by some applications for legacy purposes.

Continuous Acquisition and Life-cycle Support Type 1 Image (.cals)

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
